Seiko SPB365 King Seiko Kam...

This year, Seiko will celebrate the 110th anniversary of its, and Japan's, first wristwatch, the Laurel, with the release of a series of commemorative timepieces including a new King Seikowatch that draws inspiration from Seiko's rich technological and design heritage. It comes a year after the return of the vintage-influenced King Seiko collection, which quickly captivated watch enthusiasts around the world thanks to its sharp lines, elegant wrist presence, and winning heritage design.

At first glance, the gradient dial enchantingly plays with light, but a closer examination reveals a design inspired by a traditional Japanese geometric pattern known as Kikkoumon, which is based on the hexagonal shape of the tortoise shell. In Japanese culture, the tortoise symbolizes longevity and prosperity, and the six-sided chelonian shape is further associated with samurai armor, as an auspicious pattern signifying strength and victory.

Moreover, the Kikkoumon is a nod to the 1960s origins of King Seiko, which was born at a facility in the Kameido section of Tokyo, once known as Kameshima, an area bounded by rivers and streams and known as "Tortoise Island." The dial pattern has tremendous depth and texture - each hexagon is in fact series of three inset hexagons, each deeper than the last and this depth is further expressed on the entire dial through a gradual darkening from the center to the edges.

It features the same elegant 37mm case and a seven-link bracelet seen in other King Seiko watches over the past year. The sharpness and angularity are inspired by the classic 1965 King Seiko KSK - the second King Seiko series and the one that defined the collection's character.
